80101412 divided by 872 
The aim is to understand the frequency of 872 in 80101412.

Moving on to step 1:
When dividing 8 by 872, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 872

On to step 2:
When dividing 80 by 872, we get 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Take the next digit (1) from the dividend and append it to 80, then repeat: 801 / 872

Moving on to step 3:
When dividing 801 by 872, we get 0 with a remainder of 801.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 801 to get 801.
Grab the next digit (0) from the dividend, add it to 801, then carry on: 8010 / 872

On to step 4:
The number 872 fits into 8010 9 times, leaving a remainder of 162.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 7848 from 8010 to get 162.
Bring next digit (1) of the dividend behind the 162 and repeat the process: 1621 / 872

Let's proceed to step 5:
The number 872 fits into 1621 1 times, leaving a remainder of 749.
Use 1 as the next digit of our solution. 
Result so far: 91.0
The remainder is 749 after subtracting 872 from 1621.
Fetch the next digit (4) from the dividend, attach it to 749 and continue: 7494 / 872

Moving on to step 6:
If we divide 7494 by 872, we get 8 and a remainder of 518.
Use 8 as the next digit of our solution. 
Result so far: 918.0
If we subtract 6976 from 7494, we get 518.
Bring next digit (1) of the dividend behind the 518 and repeat the process: 5181 / 872

Going ahead to step 7:
872 can be fit into 5181 5 times, resulting in a remainder of 821.
The number 5 becomes the next digit in our result. 
Result so far: 9185.0
Subtract 4360 from 5181 to get 821.
Grab the next digit (2) from the dividend, add it to 821, then carry on: 8212 / 872

On to step 8:
If we divide 8212 by 872, we get 9 and a remainder of 364.
Record the quotient 9 as the next digit in the result. 
Result so far: 91859.0
If we take 7848 away from 8212, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Step 9:
872 can be fit into 3640 4 times, resulting in a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 91859.4
If we take 3488 away from 3640, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 10:
1520 divided by 872 is 1 with a remainder of 648.
The next digit of our result is 1. 
Result so far: 91859.41
If we subtract 872 from 1520, we get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Going ahead to step 11:
The number 872 fits into 6480 7 times, leaving a remainder of 376.
Record the quotient 7 as the next digit in the result. 
Result so far: 91859.417
Deduct 6104 from 6480 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Let's proceed to step 12:
When dividing 3760 by 872, we get 4 with a remainder of 272.
The next digit of our result is 4. 
Result so far: 91859.4174
Subtracting 3488 from 3760 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 13:
The number 872 fits into 2720 3 times, leaving a remainder of 104.
Put 3 as the next digit of the answer. 
Result so far: 91859.41743
The remainder is 104 after subtracting 2616 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 14:
If we divide 1040 by 872, we get 1 and a remainder of 168.
The number 1 becomes the next digit in our result. 
Result so far: 91859.417431
Subtract 872 from 1040 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 15:
If we divide 1680 by 872, we get 1 and a remainder of 808.
Record the quotient 1 as the next digit in the result. 
Result so far: 91859.4174311
Deduct 872 from 1680 and we're left with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

In conclusion, the division gives 91859.4174311 with a balance of 8.08e-06.
